MACHINE FOR SWAGING SHEET-METAL SPOUTS.

Specication forming part of Letters Patent No. 53,515, dated March 27, 1866; antedated March 19, 1866.

1'0 all whom it may concern:

Be it known that I, S. F. WOODWORTH, of Iowa Falls, in the county of Hardin and State ot' Iowa, have invented a new and useful Machine for Pressing and Swaging Sheet-Metal Spouts; and I do hereby declare that the fol-4 lowing is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a rear view of my invention with the lever removed; Fig. 2, a side sectional view of the same, taken in the line w Fig. 1; and Fig. 3, a detached view of the lever pertaining to the same.

Similar letters of reference indicate corresponding parts.

This invention relates to a new and useful machine for pressing or swaging sheet-metal spouts for cylindrical vessels; and it consists in the employment or use of a fixed and a movable die arranged in a suitable standard, with a lever having an eccentric attached or formed on it, all being arranged in such a manner that the spouts may be expeditiously manufactured, and in a more perfect and uniform manner than by the present exclusively manual process.

A represents a standard, the lower part, a., of which is of taper quadrilateral form to iit into a hole of a work-bench.

B is a die, which is secured in the standard A. This die may be termed the external one, and it may be made or cast separately from the standard and secured in it by screws 0r bolts, or it may be cast with the standard all in one piece. Where dies of different sizes are required the former plan is, of course, adopted; but a cheap machine with one die only could be most economically manufactured by the latter plan.

The die B is made to correspond with the exterior of the spout to be pressed or swaged, and its upper edge, ax, is inclined, so as to admit of the blank (the piece of metal which is to be pressed into the form of the spout) slipping readily back in contact with gages or stops b to insure a proper relative position of said blank with the die.

Gis the other die, made or cast of such a form that it will tit or work into thc die B. This die O works on arod or shaft, c, in the standard A, and it has a shank or stein, d, at its rear, which projects beyond the standard, as shown clearly in Fig. 2.

D is a lever, the fulcrum-pin of which is in the upper part ofthe standard. This lever is provided with an eccentric projection, e, and also with an arm, f, as shown clearly in Fig. 3. The upper die. C, is operated by this lcver D both to perform the pressing operation and to raise the die to remove the spout.

The blanks are cut out of the proper forni, and the die O raised by pressing down the long arm of the lever, so that the larm j' will strike against the stem or shank d and cause the die O to rise and he above the die B. The blank is then placed on die B and adjusted in contact with the gages or stops b, which insures the blank having a proper relative position with the dies, so that the flange ot the spout will be of1an equal width all around. The operator then reverses the lever, so that the eccentric e will bear on the top of die C, and forces down said die, so as to swage the blank into the desired spout form.

The device is extremely simple and efficient, and will perform its work rapidly and well and insure the spouts being made in a uniform manner throughout, so that they may be iitted to the vessels with the greatest facility.

Having thus described my invention, I claim as new and desire to secure by Letters Pateiltl. The arrangement of said dies B O in a standard, A, so constructed as to t the square holes usually found in 'a tinsniiths Work-bench.

2. The dies B G, in connection with the lever D, provided with the arm f and eccentric projection c, substantially as sct forth.

3. The gages b, in connection with the dies B C and lever D, for the purpose specified;

4. Having the upper surface of the die B in an inclined position to facilitate the adjustment of the blanks thereon, as set forth.

S. F. WOODWORTH.
